That's the problem of riding offroad alone, like myself in this video, riding the Smugglers' track in the Pyrenees with a Vstrom 650, going from Alins (Lleida) to Andorra. After reaching an abandoned village called Tor, the road becomes dirt track, and then it leads to Andorra all the way long, riding about 15-20 kms, until you arrive to Andorra by the peak Pic de Coma Pedrosa (I'm not sure about the name), but it's about 2300 m. high. It was used for many years by tobacco and alcohol smugglers to smug that goods into Spain avoiding the Guardia Civil controls.
I haven't had too many troubles, but a bad fall there, with no mobile network and riding alone, it would have been a bad experience.... and the guy of the video linked in the previous post, has been very lucky too, when the bike falls over him...he could have broken some bones, and then he would have been really really f*cked.....
